DA-500
Introduction
DA-500 detects various combustible & toxic gases leaked from industrial areas for gas producers, gas users, gas reservoirs, gas by-producers, and so on, in order to prevent any accidents in advance. DA-500 converts digital signal into the 4-20mA standard current output signal which can be transmitted to various devices such as PLC, DDC, or recorder to build comprehensive gas monitoring system. Also, DA-500 provides RS-485 communication signal and alarm relay contact. DC 4-20mA standard output signal realizes max 2500m long distance output signal transmission and RS-485 communication signal realizes max 1000m long distance signal transmission.
